Python 3000 Goals for the Google Sprint

Here are some things we could work on, are working on, have worked on.

Suggested Tasks

To claim a task, please add your name to it and move it to the next section.

Make IDLE work -- there are relative import issues, perhaps others.
Work on the new I/O library (I have much interest in this but need help -- Guido); you can check http://sebulba.wikispaces.com/project+iostack+v2 for a reference on what was generally agreed in the py3k list.
When the I/O library is ready, start unifying str/unicode.
Put back nb_ <true division> slots (regular and augmented)
Py3kConversionTools: Work on tool to help convert (flag keywords like with/as, removed functions/methods: apply/{}.iter*/{}.has_key/etc) (Jeremy Hylton)
Make zip() an iterator (like itertools.izip())
Make map() and filter() iterators and make them stop at the end of the shortest input (like zip()) instead of at the end of the longest input (like itertools?)
See PEP 3100 for more ideas

Clean up comparisons. Remove the ability to order objects where it doesn't make sense. (Guido, Alex)
Unify int/long (Martin von Löwis; see http://mail.python.org/pipermail/python-3000/2006-August/003046.html)
Get rid of all references to file() in favor of open(). (Anna)
Implement PEP 3102 (keyword-only arguments) (Jiwon Seo, Brett C.)
Rewrite import in Python (Brett Cannon?, Alex Martelli?, Osvaldo Santana)
Make xrange() support longs; then rename it to range() (see http://www.python.org/sf/1472639 for all but the supporting-long part) (Neal)

Rip out classic classes (done, Guido)
Fix various unit tests that are currently failing in the p3yk branch (done, various sprinters).
Rip out the last remains of coerce (done, Neal; need to rename nb_coerce slot)
Make it so that hash can be set to None to declare an unhashable type, and to automatically do this the first time eq or cmp are overridden but hash is not (done, Guido & Alex)
Rip out reduce() (done, John Reese and Jacques Frechet)
Kill uses of has_key() in idlelib (done, John R & Jacques F).
Remove basestring.find and basestring.rfind, per [http://www.python.org/dev/peps/pep-3100/ PEP 3100] (done, Hasan -- needs to be reviewed and checked in)
